TRUNK LOCK.

.Application illed. July 7, 1923. Serial No. 650,187.

To all wlwvn. it may comerm- Be it known that I, 'MARTIN RAsMUssEN, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented new and useful Improvements in Trunk Loc-ks, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to trunklocks, and has for one of its objects to provide a lock of this character which is particularly A still further object 'of the invention to provide `a device ofthe character described which will be simple in construction comparatively .inexpensive to manufacture andV more eficient in use than those which have been heretofore` proposed.

With the above and other objects in view which will appear asrthe description proceeds, the invention consists in the novel detalls of construction and comb1nat1ons of parts more fully hereinafter disclosed andA particularly pointed out in the appended claims.

Referring to the accompanying drawings in which like refe-rence characters designate a portion of the trunk wall, as Seen from the lock in its closed position; and,

.the inside, illustrating the lock in its open position;

Fig. 3 is a view Similar to Fig'. 2, showing'I -section of prs-- elevational view 'of Fig. 4: is an-edge elevational view of the parts shown in Fig, 2 as seen from the plane indicated by the line 4 4 of the said ligure.

In the said drawings the numeral 5 indicates the wardrobe section of a trunk to which is hingedly connected in the usual manner the drawer section 6,l The said .wardrobe section, as isusual in this type of trunk, is provided with an o en upper end 7 which may be closed by t e hinged top cover section 8, as is also well known. The

,drawer section 6` is recessed as at 9 and rovided with an escutcheon plate 10, provided with a keeper pin or stud 1l, seel Figs. 2 and 3. If desired, an anti-friction roller 12 may be mounted upon the said stud 11 in order to facilitate' the operation of the parts, as will presently appear.

The companion wall of the wardrobe section 5 is likewise recessed as indicated at 13, to receivel the lock assembly 14, which may comprise a casing 15,-provided with-a pivot Y pinor stud 16, uponwhich is oscillatably mounted thelocking bolt 17. The said meinber 17 is preferably shaped substantially as shown in 2 and 3, taking the form of a portion o a flat disc which is provided with the toe 18 and with ai recess 19, which toe and recess are connected by the inclined surface 20, `as will be readily understood. The said member 17 is also provided with a substantially radial elongated slot 21, extending through it, which is adapted to re- 'ceive a pin or stud 22 carried by the lower end of the operating rod 23, which rod 1s reciprocating-1y mounted adjacent the wall of the wardrobe section by suitable straps p 24. The said rod extends upwardly beyond the open-upper end of the wardrobe section, and terminates in a suitable head 25,

,which is adapted to be engaged by a disc Y or plate member 26, carried by the top coverV will be clear from The upper portion of the said rod 23 preferably passes through a substantlally cylin-pl drical casing or housing l27, within which is mounted the coiled spring 28, the lower end of which rests a ainst the .lower end 29 of the casing 27, whievthe said sp1-ing engages Pa suits.

upper end of the' e= washer memwall of the drawer section,

ber or projection 30, carried. by the rod 23.

The lcasing 15 of the lock assembly is also provided with an arcuate slot 31, through which the 4pin 22 may pass to engage the slot 21 of the oscillating member 17, see Figs. 2 and 3. The said casing is also provided with an inwardly extending wall 32, which is adapted to act as an abutment against which the oscillating member 17 may strike to limit .its unlocking movement."` f The top of the cover member 8 is provided w1th the usual. hasp member 35, which may carry any usual and well known trunk lock 36, ada ted to en age with the escutcheon plate 3 carried y the upper as will be clear from Fig. 1.

In operation, assumn the parts to be in the position shown in ig. 1, if it is desired to close and lock the trunk the drawer section 6 is' first moved about its hinges toward the wardrobe section 5, until the two sections almost meet. The top cover section 8 lis then swung downwardly on its hinges, thereby bringing the plate or disc 26 ,into engagement with the head 25 of the rod 23, forcing the same downwardly against the compression of the spring 28. The downward movement of the said rod 23 will, through the pin and slot connection 22 and 21, cause the'arcuate movement of the lockin member 17 from its position shown in ig. 2 to that shown in Fig. 3. During this arcuate movement the toe 18 will pass behind the roller 12 carried by the pin or stud 11, and will cause leverage upon .the member 17 as its movethe said roller to be engaged by the inclined surface 20 lof themember 17. -As the movement is continued thisl engagement will cause the sections 5 and 6 to be drawn tightly together, until the roller 12 is positioned within the recess 19, as shown in Fig. 3.

Durin the downward movement of the rod 23, its pin 22 has been caused, by the arcuate slot 31, to move outwardly with res ect to the pivot 16 of the locking member 1 from the inner end of the slot 21- to the outer end thereof, as will be readily understood. This downward movement of the p1n 22 of course produces an increased ment progresses,l which leverage is applied 1n drawing the two sections intimately together. i

When the top cover section has been completely closed, its lock 36 willA be engaged with the keeple'r member of the escutcheon plate 37 in t e usual and well know manner.

The unlocking of the trunk is substanthe above, the lock 36 being first disengaged from the plate 37, and the top cover section 8 raised to the position shownrin Fig. l1. This movement releases the pressure of the plate 26 upon the head 25 of the rod 23, -whereupon the spring 28 will urge the said rod 23 upwardly and will produce a reverse movement of the oscillating member 17 to disengage its toe or extension 18 of the keeper roller 12, whereupon the drawer sectlon may be swung open to the position shown in Fig. 1.

While one form of the invention has been illustrated and described it is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit. of the invention, and therefore itis not wished to be limited to the above disclosure except as may be required by the accompanying claims.
